Philip Haddad,
Even better, the population in 2010 was around four times that of 1910.
It also appears that per capita energy use has increased exponentially during that century. The growth rate probably looks remarkably like a hockey stick, but I leave such metaphors to those who least understand them.
The Warmists claim remarkable accuracy and precision measuring global surface temperatures, but also claim hat they cannot measure the difference in anthropogenically generated heat varying by a factor of 100 or so over a century (my assumption).
It is also to be noted that thermometers in earlier years were manually read, which presupposes that they were sited in close proximity to human habitation.
For any person claiming that the influence of radiant heat from a distance is irrelevant, I suggest stepping out into bright sunlight. The radiant heat source is over one hundred million kilometers away, but a thermometer will respond by showing a clear increase in temperature when moving from shade to full Sun.
Philip, you are right. The Warmists are wrong.
Live well and prosper,
Mike Flynn.
